Wheat is a cereal crop of immense importance to us, and the demand is fulfilled at the cost of soil poisoning and contamination through a number of pesticides, herbicides and excess of fertilizers. Zero tillage has become popular among the progressive farmers and serves as an economical method to conserve soil moisture, nutrients and labor force. Mulching on the other hand has benefits of conserving moisture in the field and others. Adaptive Research Farms, Gujranwala, Pakistan have published a three year field experiment study   to evaluate the possible merits of rice mulching in the zero tillage wheat fields. The outcome of the study are very promising and can be put to practical use. The research group evaluated that rice mulching in the field not only has its own merits but it also checks the weed growing in the field as well as improves the available phosphorus (P) and potassium (K) in the field. The study was conducted over a period of 3 successive seasons (2008-2011) at the...

Organic matter is considered the most valuable asset for the agricultural soil with regard to its use in crop production and landscaping. Here is a brief list of benefits from the presence of different sources of organic matter in the soil; Benefits of Soil Organic Matter (Article cover) 1. Darker soils warm up faster in spring season. (Darker color of the soil is due to presence of humus and other types of organic matter.) 2. Dead organisms (plants and animals) in the soils are converted to mineral and humus by the action of living organisms (bacteria and fungi). 3. Decomposition of the organic matter in the soil provides a source of slow release fertilizer. 4. Dead organic matter is the source of food for soil microbes and increases their activity. 5. Aeration in the soil is improved by the presences of recognizable dead organic matter; it also opens up the soil physically. 6. Fine unrecognizable organic matter has good effect on the water holding capacity of the soil. 7. Humus in ...

Biofetilizers   are the organic fertilizers which contain living microorganisms which enhance the growth and production of the plant. Biofertilizers are getting very popular these days in Pakistan and by the passing minute the awareness of biofertilizer has been increased. We have already discussed the classification of biofertilizers .  Vermicompost Biofertilizer Now, we will see what kind of application is possible for biofertilizers; their advantages and limitations and finally a brief at the scope of biofertilizers in Pakistan agriculture system. METHODS OF BIOFERTILIZER APPLICATION They can be used either for seed treatment or soil application. 1.      Soil Treatment: �          Mix both biofertilizers in compost and leave it overnight. �          Apply this mixture in the soil at the time of sowing or planting. �          In pla...

Biofertilizer  contains living microorganisms which, when applied to soil, colonizes the rhizosphere or the interior of the plant and promotes growth by increasing the availability of primary nutrients to the host plant.   Classification of Biofertilizers (Cover) Types of Biofertilizers The various types of biofertilizers which help the plant to grow at different levels of its growth are: 1.  Nitrogen Fixing Biofertilizers 2.  Phosphate Biofertilizers      a.  Phosphorous Solubilizing Biofertilizers      b.  Phosphorus Mobilizing Biofertilizers 3.  Biofertilizers for Micro-nutrients 4.  Plant Growth Promoting Rhizobacteria 5.  Compost 1) Nitrogen Fixing Biofertilizers i. Increase soil nitrogen level ii. Fixes the atmospheric nitrogen in the soil and make it available to the plants  Examples: Azotobacter , Nostoc , Rhizobium , Azospirillum a) Azobacter i. Free living N-fixing bacterium ii. Non-leguminous pla...

A fertilizer is any organic or inorganic material that is added to a soil to supply essential plant nutrients for growth.  Chemically synthesized inorganic fertilizers are widely used.  Fertilizers enhance crop yield by 30-50% and provide micro and macronutrients to the exhausted soils . Biofertilizers Biofertilizer contains living microorganisms which, when applied to soil, colonizes the rhizosphere or the interior of the plant and promotes growth by increasing the availability of primary nutrients to the host plant.   Introduction to Biofertilizers (Cover) Biofertilizers c ontain living cells or latent cells of efficient strains of microorganisms. They are eco-friendly and cause no danger to the environment. These can also be called as "Live Fertilizer" and most commonly used in  Organic Farming/Agriculture . How Biofertilizer Work? 1. Enrich the soil with microorganisms to produce organic nutrients 2. Add nutrients through the natural processes like:   ...
